Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2,2-Trichloroethyl Chlorosulfate.
CATO supplies 2,2,2-Trichloroethyl Chlorosulfate (CAS 764-09-0), a certified reference material (molecular formula C2H2Cl4O3S, MW 247.91 g/mol) for analytical method development and quality control.
Based on its molecular formula C2H2Cl4O3S, 2,2,2-Trichloroethyl Chlorosulfate contains a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 247.91 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
